A Unified Approach to Optimal Proportional Navigation
A unified approach to optimal proportional navigation for missile is purposed based on guidance performance according to the case of attacking the target without any maneuverability. The mathematic model of guidance system is built according to nonlinear relative movement relationship between missile and target, based on zeroing relative distance and zeroing the rate of line of sight. Due to the model, the optimal true proportional navigation law of guidance system is derived by using optimizing the linear quadratic performance in the case of intercepting nonmaneuvering target, at the same time the unified optimal proportional guidance law is obtained according to optimizing the different linear quadratic performance. Finally, the target is intercepted applying the guidance law through the mathematic simulation, the performance of guidance system under two optimal proportional guidance law is compared on a common basis.
